Specification forming part of Letters Patent No. 38,428, dated May 5, 1863.

, To a/ZZ whom, it may concern:

Be it known that I, DANIEL E. TEAL, of Norwich, in the county of Chenango and State of New York, have invented a new and useful Improvement in Chairs; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which- Figure l is a rear view of the chair in its upright position, showing the arrangement of the spring beneath the posterior part of the seat. Fig. 2 is a front View of the chair in its leaning or recumbeut position.

Like characters denote corresponding parts in the several iigures.

The nature of my invention consistsin constructing a chair for ordinary uses in an upright position, but suited to meet a universal want in its adaptability to tilt backward when desired without having its front legs raised or any strain thrown upon its hinder legs, thus preventing all injury to the chair as well as to the person seated upon it in his attempt to assume a recunibent attitude.

To enable others skilled in the art to make and use my invention, I will proceed to describe ils construction and operation.

A is the superior part of the chair, or chair proper, differing in no essential particular from chairs in common use. Bis the inferior or lower part of the chair, combining the seatframe, legs, and braces of an ordinary cha C C are coil-springs, each having its points of attachment to the frame B and seat A at d d d el in the rear of a line drawn transversely through the center of the seat of Ythe chair.

Springs of other kinds may be used with various modifications of arrangement to produce the same result in accordance with the nature of this invention.

I am aware that chairs have been made for the uses of dentists and of barbers with appliances for elevating and depressing the head of the patient or sitter by meansof ratchets, set pins, screws, and other suitable devices; and I am also aware that rocking-chairs are adapted to such movements without changing the position of the chair-legs in relation to the rockers beneath them. These I do not claim 5 but What I have invented, and desire to secure by Letters Patent, is-

The combination of the seat A, the springs C C, or their equivalents, and the frame B, adapted to tilt back at the will of the sitter against the resistance of the springs, substantially as shown and described.

DANIEL E. TEAL.
